LISTER-HARROW.

To all whom it may concern Be it known that I, J OHN KIEL, a citizen ofthe United States, residing at Moline, in the county of Rock Island andState of Illinois, have invented certain new and useful Improvements inLister-I'Iarrows, of which the following is a specification, referencebeing had therein to the accompanying drawing.

My invention relates to an improvement in harrows, more particularly ofthat type known as lister harrows employed in cultivation between rowsof growing plants.

The object of my invention is to provide -eans for the better protectionof plant rowth against possible injury during cultiation.

Referring to the drawings in which similar numerals indicate identicalparts Figure 1 is a perspective view of a harrow embodying myimprovements, and Fig. 2 is a plan View of Fig. 1.

The harrow frame 1 is composed of sidebars 2 and 3 inclined upwardly attheir forward ends and connected by a cross-bar 4 which may be integralwith the side bars 2 and 3 or formed separately as shown. The tooth-bars5, 6 and 7 are rockably mounted on the side-bars 2 and 3, beyond whichthey project, and are bent to conform approximately to the cross groundline between vegetation cultivated in rows; consequently the endportions of the tooth-bars 5, 6 and 7, are in a higher plane than theside-bars 2 and To prevent injury to the plants, between rows of whichthe harrow is used, I provide fender-bars 8 and 9, one on each side ofthe harrow, secured forwardly to the sidebars 2 and 3 and projectingoutwardly therefrom to clear the ends of the tooth-bars, and
